Description

The CDD4 Series CO2 transmitter uses a highly accurate and reliable Non-dispersive Infrared (NDIR) with state-of-the-art digital linearization and temperature compensated circuitry in an outside mount to detect CO2 levels and provides a linear analog signal output of 4-20 mA, 0-5 or 0-10 Vdc signals. The CDD4 is available with a range 0-20,000 ppm (Dual-channel). Parameters are set up via the concealed LCD display. Various precision thermistors or RTD’s are also available as an optional temperature output.

Features

Menu driven set-up
20,000 (Dual-channel) PPM CO2 range
Patented self-calibration algorithm
Guaranteed 5 year calibration interval
Optional Temperature Sensor Outputs
Easily field calibrated
